Accurate fault location on transmission line is important in ensuring consistent and reliable operation of the power deliver to long distance destination. Conventional methods for locating fault on transmission lines based on travelling wave and impendence-based methods usually suffer from large error due to the complexity of fault modeling on diff...
Article
Fault location is one of the important schemes in power system protection to locate the exact location of disturbance. Nowadays, artificial neural networks (ANNs) are being used significantly to identify exact fault location on transmission lines. Selection of suitable training algorithm is important in analysis of ANN performance. This paper prese...
Article
Faults in power distribution system are important to be detected, classified and located to ensure the power supply can be restored in the shortest possible time. The conventional fault classification technique, which is using steady state component, is obviously affected by many factors especially surrounding conditions. Thus, it is important to p...

Welded joints are widely used in automotive industry in order to form a complete vehicle. The welded joints not only provide connections between components but are essential in controlling the dynamic characteristics of the vehicle. The dynamic characteristic of the vehicle is highly influenced on determining the level of car Noise, Vibration and H...
Conference Paper
Transmission lines are subjected to many kind of fault. Therefore fault location scheme is needed to determine the exact location of fault. This paper proposed a method for estimating transmission line fault location system using traveling wave method and artificial neural network (ANN). The method starts by decomposing the current signal from the...
Conference Paper
Power system protective relaying is an important feature for efficient and reliable power flow operation. The traditional fault classification scheme using the steady state component is easily affected by environment factors. Then, it is important to provide power protection scheme that offers a better classification performance based on fault-gene...
Article
Fast and accurate fault classification in transmission lines is important for any protection devices. The present of extra transient signals cause to phase misclassification and malfunction of protection devices. Thus, it is crucial to provide a proper protection scheme that offer a good classification performance when the signals are influenced by...

The feasibility design and development methods of silicon microfabricated beam expander are described. Silicon bulk micromachining fabrication technology is used in producing features of the structure. A high-precision complex 3-D shape of the expander can be formed by exploiting the predictable anisotropic wet etching characteristics of single-cry...
Conference Paper
Fault in the transmission line network initiates a number of unpredictable parameters. These parameters influence the Least Square Algorithm (LSA) implemented in digital protective relays for estimating fundamental frequency phasor. The sensitivity analysis method is applied for analyzing the degree of influential parameters since the investigated...

SUMMARY Measurement algorithm is the important element of Intelligent Electronic Devices (IEDs) used in protection and monitoring of transmission and distribution networks. The function of the measurement algorithm is to estimate fundamental frequency component (phasor) of current and voltage signals recorded during network faults. The estimated fu...
Conference Paper
Implementation of uncertainty and sensitivity analysis for testing measurement accuracy of a commercial Intelligent Electronic Device (IED) requires unaffordable number of an IED tests. The main reason is a large number of factors (i.e. high dimension of factor space) that potentially affects the accuracy. The factor values are sampled within pract...
Conference Paper
An important element of any Intelligent Electronic Device (IED) is the phasor measurement algorithm. The role of such algorithm is to extract fundamental frequency phasors from signals measured on secondary winding of a current transformer (CT). As a result of faults and switching in primary network we can expect to have current signals with high a...
Conference Paper
This paper presents a novel methodology for automated testing of fault locator algorithms and testing their output sensitivity. The proposed methodology is based on Quasi Monte Carlo technique implemented in SIMLAB. The proposed methodology interfaces among SIMLAB, MATLAB and EMTP/ATP programs. A case study with a number of simulated fault location...
Conference Paper
Input voltage and current signals measured by digital protective relays during fault conditions may contain oscillatory components with different frequencies as well as transient offset. Most of the relays are using only fundamental frequency component to detect a fault condition, and other components are considered nuisance. The sources of these n...
